Question 570

Original unofficial RHEL 10 RHCSA skill-check scenario: A production volume group needs additional capacity and a new spare PV is ready. Which observation best confirms the intended outcome?

  1. `vgs` shows increased free extents and existing LVs remain available.
  2. `vgs` shows the new group with the expected total free capacity.
  3. The new partition fits in unused space and existing partitions remain unchanged.
  4. `mount -a` or the relevant validation reports no missing-volume errors.

Explanation

Correct Answer

A:

In this RHEL 10 system administration case: A production volume group needs additional capacity and a new spare PV is ready. Underlying reason: Adding a PV expands the capacity pool without automatically resizing LVs. The most direct, approved resolution is: Add the approved PV to the existing VG with `vgextend` after checking its state. Confirm it by checking: `vgs` shows increased free extents and existing LVs remain available. Sustain the fix by: Track free VG space after each expansion. This is the INTENDED response for the strongest objective verification result. It is a knowledge-check explanation, not a verified hands-on Red Hat exam answer;

Incorrect Answers

B:

`vgs` shows the new group with the expected total free capacity. That is not sufficient for the reported RHEL task, because adding a PV expands the capacity pool without automatically resizing LVs.

C:

The new partition fits in unused space and existing partitions remain unchanged. That is not sufficient for the reported RHEL task, because adding a PV expands the capacity pool without automatically resizing LVs.

D:

`mount -a` or the relevant validation reports no missing-volume errors. That is not sufficient for the reported RHEL task, because adding a PV expands the capacity pool without automatically resizing LVs.

Question 571

Original unofficial RHEL 10 RHCSA skill-check scenario: A production volume group needs additional capacity and a new spare PV is ready. Which system administration principle best explains this behavior?

  1. A volume group pools storage extents from its member physical volumes.
  2. A disk's nominal size includes storage already assigned to other partitions.
  3. Startup mount configuration can outlive the block device it references.
  4. Adding a PV expands the capacity pool without automatically resizing LVs.

Question 572

Original unofficial RHEL 10 RHCSA skill-check scenario: A production volume group needs additional capacity and a new spare PV is ready. Which ongoing practice best prevents a recurrence?

  1. Track free VG space after each expansion.
  2. Document member PVs and expected VG capacity.
  3. Validate free-space geometry before partition growth.
  4. Include fstab review in every storage retirement checklist.

Question 573

Original unofficial RHEL 10 RHCSA skill-check scenario: An administrator assumes one VG can be built from a partition already used by another VG without changing its ownership. Which action best addresses this situation?

  1. Inspect `pvs` and select only unassigned, approved PVs for the requested group.
  2. Review the desired extent size before VG creation or plan a supported migration rather than changing geometry blindly.
  3. Inspect actual free extents and partition boundaries before adding the smaller approved partition.
  4. Verify disk identity and existing partitions with `lsblk` before creating a GPT partition on the new unused device.

Explanation

Correct Answer

A:

In this RHEL 10 system administration case: An administrator assumes one VG can be built from a partition already used by another VG without changing its ownership. Underlying reason: A physical volume cannot simultaneously be an independent member of competing VGs. The most direct, approved resolution is: Inspect `pvs` and select only unassigned, approved PVs for the requested group. Confirm it by checking: Each PV belongs to the intended VG and no live group loses membership. Sustain the fix by: Enforce exclusive ownership checks on storage devices. This is the INTENDED response for the best approved troubleshooting or configuration action. It is a knowledge-check explanation, not a verified hands-on Red Hat exam answer;
